Sending float value by MODBUS TCP - NB TW01B and S7 1200
gclshortt replied to owerel209's topic in Other Omron Software
https://support.industry.siemens.com/tf//WW/en/posts/send-real-floating-values-to-client-with-modbus-tcp/144597?page=0&pageSize=10 " Note also that Modbus only works with 16-bit registers, so transferring a REAL value (32-bit IEEE format) will require you to send 2 contiguous Modbus registers and reassemble them as REAL values in your partner " In the PLC are you putting together the two 16 bit registers and then interpreting them as a float? I would look at inputting the integer number and decimal number separately on the HMI. Then use the PLC to interpret the data. Just a thought. Regards, Garry -

Thanks for the bit of levity. -
Thanks for the information gtsuport. Garry

The C40P is an expansion unit. Do you have the full part number of the unit? If this is an expansion it will connect to the K series CPU unit. The K series would then be programmed with the host link unit and software as gtsuport mentioned. You can also use a handheld unit. Most of the parts can still be obtained from EBay. https://accautomation.ca/purchase-find-parts/omron-c20k-c28k-c40k-c60k/#Special Regards, Garry

Comparison of Mitsubishi, Allen Bradley & Siemens
gclshortt replied to Gibblet's topic in General Topics - The Lounge
+1 drforsythe Very good answer. Another question is how they are investing in the IIoT. MQTT? Regards, Garry -
I would look at AdvancedHMI. https://www.advancedhmi.com/index.php?main_page=index&cPath=2 What is AdvancedHMI? Free software that will run on a windows PC and communicate to your PLC. The drivers have been written for AB PLCs. See the link below for a demo on connecting. The package was written in VB.net and runs on Visual Studio. It is then very easy to connect and update a database. https://www.advancedhmi.com/index.php?main_page=page&id=14&chapter=0 Regards, Garry

+1 Bits N Bytes Are you using a USB to Serial from the computer and then the cable into the PLC? If so then not all USB to serial cables will work. I have had success with the Ugreen cable. https://www.ugreen.com.cn/products/usb-2-0-to-rs232-serial-cable?variant=15398911737901 https://accautomation.ca/omron-cp1h-establish-communication/ This link will take you through the process of communicating serially to the CP1H. (RS485) It will be similar. Regards, Garry

Hi Evan, I have not seen this before with CX-Programmer, but I have with other programs. Call up the windows task manager. Then select Applications. If you right-click on the CX-Programmer and select maximize the application should then be seen. Let us know how you make out. Regards, Garry

~4 Line LED display over ethernet/ip recommendations
gclshortt replied to I_rock_well's topic in Allen Bradley / Rockwell Automation
https://cdn.automationdirect.com/static/specs/viewmarq4line.pdf The above will support Modbus TCP through the ethernet port. You could also look at an EA9-RHMI unit. An HDMI cable would attach to a large screen TV monitor. This would come in under your budget price and give a good display inside the plant. https://www.automationdirect.com/c-more/headless-hmi I hope this helps you out. Regards, Garry -
Choosing PLC - Not Sure if I need Open Drain or Collector

Hi Jeroen, Is it possible that the Mov(021) #9 D1 was actually @Mov(021) #9 D1? The difference is the differentiate up which means a one-shot on the move. Just a thought. Regards, Garry

https://assets.omron.eu/downloads/manual/en/v118_na_series_programmable_terminal_software_users_manual_en.pdf I assume this is an Omron NA Series HMI. What about using popup pages instead of the alarms. It looks like you have more flexibility in the display. Just a thought. Regards, Garry

Looking for a gateway from Ethernet to 16in/16out digital I/Os
gclshortt replied to Mrs.PLC's topic in Other PLCs
Yes, you can find PLCs that will work with several universal protocols. As mentioned the Click PLC would be the least investment. It can be read from Ethernet IP, Modbus TCP (Ethernet), Modbus RTU (Serial) or any customized Serial communication. It can use Modbus TCP and Modbus RTU as masters to read information from other controllers. https://accautomation.ca/modbus-rtu-click-plc-master-to-brx-plc-slave-communication/ https://accautomation.ca/click-plc-send-and-receive-instructions/ The BRX PLC (Do-More) also has the above protocols that you can read, but it can also be used to collect data from Ethernet IP, Modbus TCP, Modbus RTU, and MQTT. https://accautomation.ca/brx-plc-serial-communication-modbus-rtu-to-solo-process-temperature-controller/ https://accautomation.ca/modbus-rtu-brx-plc-master-to-click-plc-slave-communication/ https://accautomation.ca/brx-do-more-simulator-mqtt-publish-subscribe/ https://accautomation.ca/brx-do-more-plc-mqtt-communications/ It depends on what you want to communicate and the protocols you want to support.

gclshortt replied to Mrs.PLC's topic in Other PLCs
https://www.automationdirect.com/adc/overview/catalog/field_i-z-o/stride_i-z-o Stride field IO has a variety of options. See the link above. What about just using a Click PLC. https://www.automationdirect.com/adc/shopping/catalog/programmable_controllers/click_series_plcs_(stackable_micro_brick)#Series_ms=%22CLICK%20Ethernet%20Standard%22&start=0 The standard Ethernet port on the click will communicate Ethernet IP, Modbus TCP, etc. You can then add the additional IO that you want. The digital cards can be NPN or PNP. Software is free and you can just use the PLC for its IO reading and writing. Regards, Garry -

https://assets.omron.eu/downloads/manual/en/v4/w465_cs_cj-series_ethernet_ip_units_operation_manual_en.pdf The following section may apply for CJ2M to CJ2M communications: 6-1 Overview of Tag Data Links 6-1-1 Tag Data Links Tag data links enable cyclic data exchanges on an EtherNet/IP network between PLCs or between PLCs and another device. I/O memory addresses (e.g., in the CIO or DM Area) and symbols can be assigned to tags. The settings for tag data links are made using the Network Configurator. The above is for ethernet. You would have to add additional cards. http://forums.mrplc.com/index.php?/topic/37334-omron-cj2m-cpu13-serial-port-communication/ https://www.edata.omron.com.au/eData/PLCs/CJ2/W472-E1-14.pdf The above thread will help with serial communication.

http://www.plctalk.net/qanda/showthread.php?t=123751 The same question was posted at the above location. It sounds like you have a C20K or C20 series Omron controller. The full part number should be printed on the top or side of the PLC.Yes, your program is lost.The only way to restore it is to reload from a paper copy or backup if you have it.You will have to replace the battery, or your program will not be saved in the ram memory.These controllers also have the ability of an EPROM. This is located under a hatch on the top of the CPU. If the socket is not empty, there is a chance the program might be on it.https://accautomation.ca/omron-c20k-...oubleshooting/https://accautomation.ca/purchase-fi...28k-c40k-c60k/ Regards, Garry

You have not specified all of the hardware that you have. http://www.ia.omron.com/data_pdf/cat/cj1w-scu_ds_e_9_1_csm2151.pdf The Omron will act as a Modbus RTU slave to the Schneider Modbus RTU master. Here is the manual for the Omron communication module. https://assets.omron.eu/downloads/manual/en/v1/w336_cs1_cj1_serial_communications_boards_operation_manual_en.pdf You will find the Modbus addresses on page 58. Modbus-RTU Slave Mode What is the Schneider device that you will use? It must be able to be set up as a Modbus Master. I hope this helps you out. Regards, Garry
